  • Patent number: 9723539
    Abstract: A relay wireless communication device is discovered using probe request. A source device that intends to transmit one or more frames to a destination device transmits the probe request to request a probe response from one or more potential relay devices. A relay device transmits a probe response to the source device when the relay device may operate to forward the one or more frames from the source device to the destination device. The relay device employs one or more considerations to determine its eligibility to serve as relay for the source and destination devices. The source device selects one of the potential relay devices based on their provided probe responses. The source device may select an optimal relay device based upon two or more received probe responses.

  • Patent number: 9722755
    Abstract: A method and apparatus for transmitting or receiving channel quality control information through a physical uplink shared channel (PUSCH) in a wireless access system that supports hybrid automatic retransmit request (HARQ). In one embodiment, a user equipment (UE) receives a physical downlink control channel (PDCCH) signal including an initial uplink grant, transmits uplink data using two transport blocks based on the initial uplink grant, receives a negative acknowledgement (NACK) information for one of the two transport blocks, and transmits a channel quality control information along with the one of the two transport blocks which is retransmitted according to the NACK information or a new transport block through the PUSCH to which the HARQ is applied. A number of coded symbols required to transmit the channel quality control information (Q?) is calculated based on the initial uplink grant.

  • Patent number: 9716570
    Abstract: The purpose of the present invention is to inhibit an increase in the amount of A/N resources, without changing the timing at which the error detection result of an SCell is notified when UL-DL configurations to be configured for each of the unit bands are different, from the timing at which the error detection result is notified when just a single unit band is configured. A control unit (208) transmits, using a first unit band, a response signal including error detection results about data received with both the first unit band and a second unit band. In a first composition pattern set for the first unit band, an uplink communication subframe is set to be the same timing as at least an uplink communication subframe of a second composition pattern set for the second unit band.

    Abstract: Methods and apparatus for network setup in wide channel WLANs are provided. Techniques for co-existence of 20 MHz and 40 MHz networks (e.g., as defined by IEEE 802.11n) may be extended to 80 MHz and 160 MHz networks. For example, a primary channel of an existing network may be designated as the primary channel of a new network. Further, a primary channel of the existing network may not be used as a secondary channel in the new network. Intolerance operation between networks may include a first network releasing one or more channels in response to an intolerance indication received from a second network. Furthermore, in response to the intolerance indication from the second network, the first network may utilize one or more channels for communicating in the first network using a first set of access parameters. The access parameters may depend on the intolerance indication.

  • Patent number: 9705658
    Abstract: In order to support low latency and bursty internet data traffic, the 3GPP LTE wireless communication system uses dynamic allocation. To keep the allocation overhead lower, the system is designed such that the client terminal must perform a number of decoding attempts to detect resource allocations. During course of the decoding attempts a false resource allocation may be decoded by the client terminal. The false detection may lead to multiple issues for the performance efficiency of the client terminal and the overall communication system. A method and apparatus are disclosed than enable the detection of false resource allocation. This in turn improves the performance and efficiency of the client terminal and the wireless communication system.

  • Patent number: 9668226
    Abstract: The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving, at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating, by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.

  • Patent number: 9647823
    Abstract: Methods, systems, and devices are described for wireless communication at an access point (AP). A scheduling procedure for using a full duplex wireless local area network (WLAN) AP with legacy station (STA) compatibility (e.g., half duplex) may be implemented. For example, a system may include a full duplex AP and have half duplex STAs with two antennas each. The scheduling procedure may involve dynamic grouping of STAs into half duplex sets, for example, based at least in part on location information of the STAs. The STAs may be grouped such that the AP is able to transmit to one of the half duplex sets while concurrently receiving from another of the half-duplex sets. The AP may employ beamforming, via the STAs, to reduce interference between full duplex in-band communications.
